8 Claims.

This invention relates generally to shaving devices for cutting whiskers or other hair from the skin withoutthe use of any applicator to the skin,- but more specifically to a cutting, head for such a device which has a double row of cutting teeth operating successively during passage of the cutting head over the skin.

The main object of the invention resides in the provision of a cutting. head having a central and longitudinal opening whereby the operative surface of the cutting head affords two spaced rows of cutting teeth operating simultaneously and adapted to pass over the same skin areas during movement of the cutting head.

Another object of the invention resides in the provision of a cutting head having an operative surface which is adapted to be placed'on the skin and wherein the handle therefor is disposed in a plane substantially parallel to the said operative surface.

A further object of the invention resides in the provision of a cutting head which is economical to manufacture, simple to operate and highly efiicient in operation.

These objects and other incidental ends and advantages will hereinafter appear inrtheprogress of the disclosure and as pointed out in the appended claims.

Accompanying this specification is a drawing showing a preferred embodiment of the invention wherein corresponding reference characters designate corresponding parts throughout the several views and wherein:

Figure 1 is a side view of an assembled razor with handle embodying my invention.

Figure 2 is an end elevation of the upper portion of Figure 1.

Figure 3 is an enlarged view of the cutting head portion of the razor shown in 'Figure 1.

Figure 4 is a sectional view of Figure 3 through the plane 4-4 thereof.

Figure 5 is a top plan view of the stationary cutter member of the cutting head.

Figure 6 is a sectional view of Figure 5 through the plane 66 thereof.

Figure '7 is a. top plan view of the movable cutter of the cutting head.

Figure 8 is a sectional view of Figure '7 through the plane 8-8 thereof.

Figure 9 is a detail perspective side view of the handlev or carrier to which the cutting head is attached and illustrating the actuating member for the movable cutter.

In accordance with the'invention and is accordance with the preferred form thereof shown oscillate longitudinally of channel I2 an actuat- 10 ing arm I5 having a bend I6 terminating into channel I2 for operative engagement with the movable cutter member I4.

The stationary cutter member is preferably comprised of a section of steel tubing which is usually made of sheet metal and each of whose sides is unifo'rm in thickness and as shown is square in shape, the side containing spaced teeth I], which latter extend downwardly along the side walls, being provided with an opening I8 disposed longitudinallyof the cutter member and intermediate the width of the side memtioned. Cutter member I3 is provided with a central orifice I9 on the wall opposite to the toothed wall and is of a size sufficient to receive the end of the actuating arm I5 and permit oscillation thereof within the said orifice. The stationary cutter member I3 is also provided with orifices 20 and 2i adjacent to andon the same wall as-orifice I9, the said orifices 20' and M engaging securing lugs 22 and 23 situated on the rear upright wall of channel I2. The rear upright wall of channel I2 is also provided with a central opening 24 to permit insertion there through of portion I6 of actuating arm I5.

When thestationary cutter member I3 is inserted in channel I2, orifices I9 and 24 are in alignment while orifices 20' and 2| engage lugs 22 and 23 respectively thereby securing the cutter in the channel. penetrates the upper wall of channel I2 and impinges against the top wall of cutter I3 as best; shown in Figure 4.

The movable cutter I4 is comprised of a sec- Aset screw 25 is also provided which 40 tion of steel tubing similar in shape to the stationary cutter I3 and is reduced in dimensions to reciprocate within the latter. The cutter I4 is provided with a central and longitudinal opening 25 intermediate the width of the wall or side containing teeth 21, the opening 26 being adjacent 5 to the opening I8 of the stationary cutter when the cutters are assembled for operation. A central orifice 28 is provided on the opposite wall of cutter I4 and is adapted to engage end 20 of actuating arm I5.

The assembly and operation of the aforementioned shaving device is indeed very simple.

Moreover, the manufacture of the cutting head consisting of the stationary cutter member l3 and the movable cutter member I4 is accomplished very easily and economically by applying a series of spaced grooving cutters to the operative walls of the tubular cutter members thereby resulting in the formation of two rows of cutting teeth oppositely disposed of the longitudinal openings.

In order to assemble the cutting head in channel l2 for operation, the movable cutter I! is fitted within the stationary cutter l3 so. that orifices 28 and I! are in alignment. In such position, the two cutters are inserted into channel l2 of handle I 0 so that end 20 of actuating arm l6 penetrates both orifices. Lugs 22 and 23 are made to engage orifices 20' and 2| situated in the rear wall of stationary cutter I The faces of lugs '22 and 23 form a continuous surface with the rear wall of stationary cutter l3, thereby permitting reciprocal motion of the movable cutter i4 within the stationary cutter l3. A set screw 25, having first been elevated from channel l2 to permit insertion of the cutting head, is now tightened to impinge against the top wall of the stationary cutter l3, thereby securing the latter fixedly in place.

In operation, the stationary cutter is pressed against the skin, so that the teeth lying in the plane parallel to the rear wall of the cutter containing orifices I 9, 20 and 2|, lie against and coplanar with the skin. When the cutting head I3, is passed over the skin, the hairs are combed into the grooves between the teeth I! by virtue of the outer corners of the teeth formed by the intersection of the side containing the spaced teeth I! and the adjacent side walls. Since the movable cutter H, which is similar in construction to cutter l3 except that there are less teeth and wider resultant grooves, oscillates rapidly within the stationary cutter, at any given instant a number of grooves in i4 coincide with the grooves in stationary cutter l3. In this position the hairs which pass thru the grooves in the stationary cutter l3, pass on into the coinciding grooves in movable cutter ll. When movable cutter ll continues its movement in a plane at right angles to the axis of the hairs, the grooves in I move away from the coinciding grooves in i3 and thus shear the hairs oif between the upper surface The depth between the wall containing spaced teeth I! of the stationary cutter and the rear wall of the movable cutter determines the length of hair that can be cut'by the cutting head. Morover, the thickness of the wall of the stationary cutter containing teeth I! determines the depth of cut for each hair.

The purpose of the aligned openings is to 'divide the cutting members into two parts, so as to have two rows of cutting teeth, one following closely behind the other, allowing for a shave and ieshave in one operation.

I wish it understood that minor changes and variations in the position, integration, material, conformation and combination and subcombination of parts may all be resorted to without departing from the spirit of the invention and without departing from the scope of the appended claims.
